jtree

I know you can create a table and add a JTree as a column . But what I want to do is the complete opposite. Check the image and tell me if this is possible. Thanks! UPDATE: By using MKorbel's code and by randomizing the number of columns with the following code: @Override public int getColumnCount() { int i = (int) (Math.random( )* 10.0); if (i%2 ==0) return 2; else return 3; } I was able to get the following image: mKorbel 1) I didn't solve isLeaf() in Renderer and Editor somehow 2) if I put JScrollPane with JTable to the Node directly, (without using JPanel as parent ) then JTree View isn't

I need an example how to add a keyboard handler that detect when Ctrl + C , Ctrl + X , Ctrl + C pressed on a JTree . I were do this before with menu shortcut keys but with no success. You can add KeyListeners to any component (f) f.addKeyListener(new KeyListener() { @Override public void keyTyped(KeyEvent e) { } @Override public void keyPressed(KeyEvent e) { if ((e.getKeyCode() == KeyEvent.VK_C) && ((e.getModifiers() & KeyEvent.CTRL_MASK) != 0)) { System.out.println("woot!"); } } @Override public void keyReleased(KeyEvent e) { } }); MOHAMED FATHEI Use KeyListener for example : jTree1

First of all, let me say that I dont use the DefaultTreeModel. I implement my own TreeModel, so i cant use the DefaultXXX stuff. The problem is this: Through some addStuff() methods which my model defines I add nodes to the underlying data structure. I then notify listeners by calling treeNodesChanged() inside the addStuff() function (I Know there are treeNodesInserted methods but it is the same thing. It just notifies listeners with a different method). Now, one of the listeners is a static class in my main form and this listener can tell the JTree, which is also contained in my main form, to

I've got a custom tree cell renderer that I'm using to render custom icons a JTree, and I really like the warning icon and the error icon that JOptionPane displays for both warning messages and error messages respectively. Obviously I can use the following code to get the icons for my own use, but this is way heavy handed and requires me to instantiate dialogs that I'm never going to use: public class ValidationCellRenderer extends DefaultTreeCellRenderer { private Icon warnIcon; private Icon errorIcon; public ValidationCellRenderer() { JOptionPane optionPane = new JOptionPane(new Object(),

I would like to have a way to display the contents of an XML file in a JTree . I have already accomplished this using DOM, by implementing a custom TreeModel (and TreeCellRenderer ). However it is very clunky (much workaround-ery and hackery) and rather rough around the edges. Is anyone aware of a way to get a JTree to display the contents of an XML file, parsed with SAX? Thanks! Here's the code that I use. It is based on the API of Dom4J, but you can easily convert it to the APIs of your favorite XML library: public JTree build(String pathToXml) throws Exception { SAXReader reader = new
